Jambú
Jambú is both a spice and an herb, derived from the leaves and flower buds of Acmella oleracea, an Amazonian herb in the daisy family (Asteraceae). Chewing it sets off a tingling and numb feeling due to the compound spilanthol. This is why the plant is also called the electric daisy, and the buds are called buzz buttons (see below). Beyond Brazilian cuisine, it’s also heavily used in Madagascan, or Malagasy, cooking, where it’s called brèdes mafana.
